Novel resin, method for producing the same, novel composition, and cured product obtained by curing the composition

摘要

The resin of the present invention has a molecular chain in which a plurality of organic groups represented by the following formula (I) are bonded, and has a weight average molecular weight of 10,000 to 300,000. (In the formula, C is a divalent organic group having a divalent hydrocarbon chain having 30 to 50 carbon atoms, and A is an amide bond, ester bond, urethane bond, urea bond or carbonate bond.) . According to the resin of the present invention, UL-94 VTM-0 level flame retardancy can be exhibited even when a halogen-containing flame retardant and a phosphorus flame retardant are not used, and UL-94 VTM. A cured product having flame resistance of −0 level can be easily obtained.
